Use algebra to evaluate the limit of lim h>0 (2h)^38/h.
Is the answer 12

drwls,
Is 3  8/h all an exponent of 2h, or are you taking the difference of two terms, (2h)^3 and 8/h? You should use parentheses to clarify this.
If 8/h is a separate term, 12 is not the answer. The limit of 8/h as h> 0 is infinity.
